×=167
180-12=168
× and 13 are linear pair so together they equal 180
Hey there!
(9) 2x-9y=45
... -9y=-2x+45
... y = (2/9)x - 5
Slope = 2/9
y-intercept = (0,-5)
(11) 3y+2x=-15
... 3y=-2x-15
... y = (-2/3)x - 5
Slope = -2/3
y-intercept = (0,-5)
(12) 10x+8y=40
... 8y=-10x+40
... y=(-10/8)x+5
Slope = -5/4 (after simplifying )
y-intercept = (0,5)
Hope my answer helps!
Answer:
7 x 9 = 63, 63 divided by 2 = 31.5,
31.5 x 4 = 126
9 x 9 = 81
Add given areas:
126 + 81 = 207 in2 is your answer
Answer:
C - a stack of 15.6 watermelons
Step-by-step explanation:
Lets first go through each option:
<u>"A shopping receipt that totals $4.90"</u>:
This is an appropriate answer since many items sold are not priced at exact dollars (where there are no cents), so having $4.90 as the total cost after shopping is appropriate.
<u>"A soccer game where the average score is 4.7"</u>:
This is also an appropriate result since it is the <em>average</em> score of a soccer game, so finding a decimal is appropriate.
<u>"A stack of 15.6 watermelons"</u>:
This is not an appropriate result since it would be strange to say a 'stack' or group of something that is not a whole number.
<u>"A classroom with 24 students"</u>:
This is an appropriate result since the number of students is a whole number not a decimal.
Hope this helps :)
Answer:
b= 25
Step-by-step explanation:
a+b =72
a-b = 22
2a = 94
DBS(Divide Both Side) by 2
a = 47
=47 +b =72
and:
47 -b =22
subtract 47 from both sides:
b=25
and
-b = -25 MBS(Multiply Both Side) by-1 ....>b=25
